Beijing Oriens Technology Co., Ltd. is a reliable extruded aluminum heatsink manufacturer in China

Beijing Oriens Technology Co., Ltd. is a China-based heatsink manufacturer in Beijing, founded in 1998, 25+ years of producing and exporting experience. ORIENS specializes in extruded aluminum profile heatsinks, supplying OEM and ODM customers in the US, Europe, Africa and South Asia with both standard profiles and fully customized designs.

Here are some real inquiry questions and answers during procurement, which have reference value

Q. What material and surface finish does ORIENS use for its extruded heatsinks?

A: ORIENS extruded heatsinks are made from aluminum alloy 6063-T5 as standard, with 6061-T6, 6005 and 6060 also available. Surface treatments include clear (natural) anodizing, black anodizing, powder coating, electrophoretic paint, chrome plating and polishing. Custom colors and laser marking / screen printing for logos are supported, and dimensional accuracy reaches ±0.05 mm on CNC-processed surfaces.

Q. Can Beijing Oriens customize the heatsink profile, fin density, and dimensions?

A: Yes. ORIENS supports full customization of extrusion profile, width, height, fin pitch, fin thickness and length.you can send 2D drawings or 3D files (STEP, IGES, CAD, DWG, PDF) or a sample to us; ORIENS provides in-house tooling design and assembly plus free samples for quality testing before mass production.

Q. What is the minimum order quantity (MOQ) when sourcing heatsinks from your company?

A: For extruded aluminum heatsinks, ORIENS accepts orders from 10 pieces, with better pricing at larger quantities. For brand-new custom extrusion profiles, typical MOQ is 500pieces; prototypes can be produced by CNC machining in small quantities before the extrusion die is built.

Q. What is the tooling cost and lead time for a custom extrusion die at ORIENS?

A: A custom heatsink extrusion die at ORIENS typically costs USD 600,depending on profile size and complexity, with in-house die design and assembly. Delivery time is 8–15 working days for stock profiles, and 15–25 days for custom designs after drawing and sample confirmation; expedited arrangements are available. Shipping is normally from Tianjin Port (train/sea DDP, air, or express are all supported).

Q. How do you verify the thermal performance (°C/W) of its heatsinks?

A: ORIENS provides thermal resistance (Rth, °C/W) values measured under stated natural-convection and forced-air conditions, and can provide material reports and dimensional reports with each order. Its inspection facilities include a three-dimensional measuring instrument (CMM), salt spray test box, dynamic balance detector and pneumatic detection, with 100% inspection on critical dimensions and appearance before shipment. our engineering team reviews fin geometry against the buyer's power dissipation requirements to optimize performance before tooling.

Q. What quality certifications and inspection standards do you follow?

A: ORIENS operates under an ISO 9001-certified quality management system (founded 1998, automatic production lines), and its heatsinks comply with RoHS requirements for export to the EU and North America. and a two-stage quality control system (production line + final inspection).ORIENS also tracks on-time delivery as a key KPI, maintaining a 99.87% on-time delivery record.

Q. What are the payment terms, trade terms, and shipping options offered by Beijing Oriens?

A: ORIENS accepts T/T, L/C, D/A, D/P, and PayPal and so on. Trade terms include FOB Tianjin as well as train/sea DDP, air and express shipping (or the buyer's own forwarder). Heatsinks are bubble-packed individually to prevent damage and scratches in transit, then packed in cartons with polyethylene protection; custom packaging and label printing (screen printing, laser marking) are available. 

Q. Which applications are your extruded aluminum heatsinks typically used for?

A: ORIENS high-density fin extruded heatsinks are widely used to cool high-performance power supplies (up to 600W), IGBT modules, solid-state relays (SSR), rectifiers, inverters, distribution boxes, LED lighting and LED street lights, telecom equipment, PCB modules, server chassis, industrial machinery and automotive electronics. The straight-fin extrusion design delivers the best cost-to-performance ratio for natural-convection and forced-air cooling in enclosed equipment.

Q. Why should overseas buyers choose Beijing Oriens instead of a trading company?

A: Buying directly from Beijing Oriens Technology Co., Ltd. means factory-direct pricing, direct communication with a professional technical team, a 25-year track record of producing and exporting, We can provide material and dimensional reports per batch, provide after-sales service in terms of quality. As a manufacturer — not a trader — ORIENS protects customer designs and information under NDA, provides free samples for quality testing, offers comprehensive OEM & ODM services, and maintains a 99.87% on-time delivery record.
